INTRODUCTIONThe BS 2 transverse conveyors are used to linkconveyor modules together. They also can be usedfor transport over shorter distances, such as theends of rectangular loops spurs, and side branches.In instances where a lighter load capacity is accept-able, such as connecting workstations or "feed-in"lines, transverse conveyors provide a simple solu-tion. By using a lift-transverse unit, BS 2 transverseconveyors allow pallets to be moved between paral-lel conveyor lines.

Under normal operating conditions, the BS 2 trans-verse conveyors have a maximum load capacity of60 kg (132 lbs) per section. The BS 2/M gains anadvantage over the standard BS 2 layout becauseits drive is positioned within the length of the con-veyor section, rather than at the end. This permits anincreased load capacity in the reverse direction. Theanti-static toothed belt is driven at nominal speeds of6, 9, 12, 15 or 18 meters per minute, depending onthe system ordered. Other options include motormounting position (inboard/outboard, right or leftside)

The BS 2/M transverse conveyor also provides amore compact design because the large drive andreturn ends are eliminated, which enables othermodules, such as lift transverse units, to be posi-tioned closer to the end.

The BS 2/M is reversible, and because of its design,can carry a 60 kg load in either direction.

The BS 2/M transverse conveyor is available inlengths up to 4900mm, and in a range of widths toaccomodate pallets from 160mm to 1040 mm. Leftor right hand outboard drive is available for all palletsizes, and pallets 240mm or larger allow an inboardversion, with the motor mounted between the rails.

Accessories available for the BS 2 transverse con-veyors that are needed in most standard installationsinclude the LE 1 foundation bracket (Fig. 1) and theSZ 2 leg set (Fig. 2).

GENERAL INSTALLATION PROCEDURES

T-slot connectors (Fig. 5)

The BS 2/M transverse conveyor, like virtually allBosch conveyor modules, is connected to the trans-fer system using the T-slot principle. For T-bolts,insert the T-bolt into the slot (A), and tighten down thehex nut. As it tightens, it will turn the T-bolt 90° in theslot (B), creating a friction lock (C). The sameprinciple applies to T-nuts. The maximum allowabletorque is 25 Nm (18.5 ft-lbs).

Assembly tip: T-bolts also have a mark on the endof the threaded shaft that will be perpendicular tothe T-slot when the bolt is in its locked position.

INSTALLING THE BS 2/M TRANSVERSE CONVEYOR

Figure 7: Connecting to Other Modules

Attaching the BS 2/M transverse conveyor to a conveyor system (Fig. 10)

The BS 2/M transverse conveyor connects to otherconveyor modules and straight segments, such asthe ST2/B conveyor section.

For all standard installations, the conveyor connects toother modules with the connector kits supplied. Theconnectors are designed to provide the proper trans-port surface height relative to connected modules.

1 When attaching the BS 2/M to a TSplus mainconveyor line, note the direction of line flow.The pallet should always move toward the driveend of the BS 2 in normal operation.

2 For 80mm TSplus conveyors or other BS2modules, use one spacer with the mountingbracket as shown in Fig. 7-A. Use one 20mmand one 50mm T-bolt as shown.

3 For 100mm TSplus conveyors, use threespacers with the mounting bracket as shown inFig. 7-B. Use one 20mm and one 50mm T-boltas shown.

Figure 8: Installing Leg Sets, (Example Conveyor of Length = 4000 mm)

Installing leg sets SZ 2 (Fig. 8)

1 The BS 2/M must be supptorted at each end, eitherby mounting brackets or leg sets. Additional legsets are required at no more than two meterintervals for conveyors in excess of two meters inlength.

2 The gussets on the leg sets are attached to the T-slots on the bottom of the conveyor rails with T-bolts. End leg sets will have gussets on only oneside (facing away from the ends). Intermediateleg sets will have gussets on both sides.

Figure 9: Leveling and Securing the Conveyor

Leveling and securing the conveyor system (Fig. 9)

1 Starting at the drive end, use a level to verifythat the conveyor is properly aligned, first fromside to side, then lengthwise. Recheck bothdirections after making any adjustments. Thelength should be checked at no more than twometer intervals between and at leg sets.

2 If any adjustment is needed, use a 24 mm wrenchtoloosen the counter nut "A". Turn the spindles ofthe leveling feet (inset) accordingly with a 13 mmwrench.

3 Once the legs are adjusted to the proper height(the conveyor is level and all feet are in firmcontact with the floor), tighten the counter-nut "A"to lock the feet at their proper height.

BS 2/M TRANSVERSE CONVEYOR MOTOR CONNECTIONS

Note: The customer assumes all responsibility forthe control system, and must provide an EMER-GENCY-OFF SWITCH for the BS 2/M transverseconveyor.

Before starting up the conveyor for the first time,recheck all mounting hardware for tightness.

Figure 11c

Figure 11d

Locate the data tag on the motor and determine thewiring connection used (Y or Delta) by referring tothe "Volts" information box on the data tag, thenfollow the appropriate connection schematic at left.

IMPORTANT! All electrical wiring must be con-nected by a qualified electrician and in accordancewith local electrical codes!

Note: The rotation marks in Figures 11b and 11capply to the rotor shaft only. To reverse the directionof rotation, transpose any two leads.

To avoid damage to the power cables, make surethat the cables are long enough to reach the cableinput on the terminal box (Figure 11d) without stretch-ing, and secured in such a way as to prevent themfrom interfering with other objects.

REGULAR MAINTENANCE

Inspection and Maintenance (Fig. 12)

Figure 12: Inspection and Maintenance Points

CAUTION! Lock out all power supplies beforebeginning maintenance work of any type!

The following cleaning and adjustment procedureswill help keep your conveyor in optimal condition ifperformed on a regular basis.

1 The sealed gearbox is maintenance free. It should,however, be inspected regularly for damage or oilleakage caused by excessive wear.

2 To ensure that the motor remains cool enough,remove all dirt and dust from the motor surface,intake opening, fan hood, and between the cool-ing fins at least once per week.

3 Check the toothed belt for wear and damage,especially at the arrow shaped weld joint. Wipethe conveyor clean of any excess grease, dirt, andany foreign substances regularly. Replace anyparts showing signs of excess wear.

4 Verify that the idle rollers rotate freely and are notdamaged. Stuck or danaged rollers will lead topremature belt failure.

Regularly check that all connectors and fastenersare properly tightened and re-tighten to their propertorque as needed.

NOTE: Before removing the old toothed belt, verifythat the replacement belt is of the proper length! Animproperly sized belt will cause poor performanceand may cause damage to the conveyor system.

CAUTION! Lock out all power supplies beforebeginning repair work of any type!

1 Carefully remove the snap-in belt guide profilefrom the aluminum profile by pulling up on theoutside edge. It may be necessary to pry it out bycarefully inserting a screwdriver between the guideprofile and the aluminum profile and gently pryingout the guide profile.

2 Loosen the four M5 x 30 socket head cap screwson each side of the two bearing housing assem-blies.

3 Loosen the two flat head phillips screws on top ofthe two return assemblies and remove retainer.

4 Carefully lift up the belt and return rollers.

5 Slide the return roller out of the belt.

CAUTION! If the drive unit is not kept level whenremoving or installing it, it may cause damage to theunit by bending or twisting the components. Also,the two sides may separate and fall, potentiallydamaging the unit and causing personal injury!

6 Carefully lift the upper bearing housings with

the motor and gearbox and remove. Usecaution handling these parts because they areNOT mechanically fastened together!

7 Remove the two idler rollers adjacent to the alumi-num profile on both sides of the bearing housing.

8 Slide the belt end guides out of the aluminumprofile and remove.

9 Lift out the old toothed belt.

Installing the new belt:

To install the new belt, reverse the steps above,making sure to:

1 Verify that the new toothed belt is properly lubri-cated. Oil the toothed surface of the belt with ahigh quality spindle oil, if necessary.

2 Make sure that the pointed end of the arrowshaped weld is pointing in the direction of forwardmovement, i.e. towards the drive unit.

3 Make sure that the eight idler rollers are free of dirtand damage, and spin freely.

4 Carefully lower the drive assembly into place,keeping it level! Secure with socket head capscrews, alternating between sides and diagonallyopposite corners on the assembly.
